| 摘要 |
The invention relates to a feed mechanism for a four-edge planing machine used for machining rectangular cross-section wooden pieces with straight or profiled milled surfaces According to the invention, the feed mechanism comprises a unique motovibrator (1) which transmits the movement, through a bicardanic transmission (10), to a first advance roller (5), wherefrom, through a tapered gearing (14), the movement is transmitted from a roller (5) to another advance roller through chains (22) and identical mechanisms comprising a grooved vertical shaft, tapered gearing (14) and driving shaft (15), to each advance roller of the chain wheel corresponding to the first and last advance roller, the movement being transmitted by chain and electromagnetic coupling (29) to the vertical threaded shafts (28) in cinematic connection with the nuts fastened in the vertical columns (4)
